Warnings and safety notes
- For your safety and a better user experience, please read this manual and follow the instruction before using the new charger.
- This is not a toy. This appliance is not intended for use by young children under 14 years of age or uninformed persons unless they were adequately supervised by a responsible adult person to ensure that they can use the appliance safely.
- Never use the charger without supervision, please stop using the charger and refer to the manual if you encounter any functional abnormality.
- Keep the charger away from dust, humidity, rain, low and high temperature, as well as avoid direct exposure to the sunlight and intense vibration.
- Place the charger on a heat-resisting, non-flammable and insulating surface. Do not use it on the car’s seats, carpet or other similar places. Keep inflammable and explosive objects away from operation areas of the charger.
- Only operate this device in a cool ventilated area.
- Read the instruction manual carefully to be familiar with the features of the charger, and set proper charging parameters before operating. Setting the parameters incorrectly and or failure to observe safety procedures may and will result in damage to the product, personal property and cause serious injury as well.
- Never attempt to charge primary (non-rechargeable) batteries.
- Batteries pose a severe risk of fire if not properly handled.
- This unit may emit heat during use.

How to confirm charging current
Make sure to know the maximum charging current of the battery before charging, never use excessive current to charge to damage your battery, which will result in over heat even explosion during the charging process. The charging and discharging rate of battery is usually mar ked with C value. Multiplying the charging C value and battery capacity equals to the maximum charging cu rrent supported by the battery. For example, for a 1000 mAh battery with a charging rate of 5C, the maximum charging current would be 1000*5= 5000mA; therefo re, the maximum charging current is 5A. For a lithium battery, if it is impossible to confirm the supported charging C value, please set the charging current below 1C, for the sake of its (lithium battery) safety. The refe rence relation between C value and charging time: char ging time ≥60 minutes/ charging C value (e.g. it needs around 60~70 minutes to complete charging with 1C). Due to differences in battery conversion efficiency, the time to complete the charging might be extended.
Operating the charger
Power on your C50 Duo charger connecting to a car battery/stabilized power supply, connect the battery, and long press the menu button of the desired channel to enter the task setting menu as follows:
| Task | Charge |
| Chemistry | ULiHV, LiHV, LiPo, LiIon, LiFe, Pb, NiMH/Cd |
| Condition | Charge terminal voltage, delta-peak sensitivity for NiMH/NiCd |
| Cells | LiFe, LiIon, LiPo, LiHV, ULiHV (1–6S); Pb (1–10S); NiMH/Cd (1–16S) |
| Current | 0.2–10.0A |
Charge
Charge Balancing port is strongly recommended when charging LiPo battery, which can make sure to monitor voltage on each cell battery and balance it when charging. Warning beeper will yell before start charging LiPo if in non-ba lance mode (no connecting with balance port).
Current setting range: 0.2–10.0A
Starting/Stopping the task
Once satisfied with your settings select "Start" and press the Menu button of the respective channel to start the task.
You can stop the task in progress anytime. Long press the Menu button of the respective channel and then select "Stop" and press the Menu button.
Advanced settings
Under the standby interface, long press the CH1 and CH2 bu ttons at the same time to enter the advanced setting menu.
Dual task
Dual task Select this setting, the charger will charge two batteries connected to Ch1 and CH2 with the same parameters at the same time. Connect the charger with the power supply and power on; select this setting on the advanced setting menu to set the task parameters.
